CS1 maint: Unfit url

This is a tracking category for CS1 citations that use |dead-url=unfit or |dead-url=usurped. The keywords unfit and usurped are intended to identify original urls that point to live sites that are inappropriate: spam, advertising, porn, etc. A url that returns a HTTP 404 error is not considered to be unfit and, in such cases, editors should set |dead-url=yes. cs1|2 templates in pages listed in this category should be checked to ensure that the unfit and usurped keywords are correctly applied. Pages in this category should only be added by Module:Citation/CS1.

While most of the Citation Style 1 and Citation Style 2 error messages are visible to all readers, some remain hidden. Editors who wish to see all of the CS1|2 error messages can do so by updating their or CSS stylesheet to include:

The above code is required if you wish to see maintenance category messages:
